There are a lot of different things that you are going to want to know if you're planning on moving to Idaho and maybe living in the Treasure Valley. Winters can be cold, so there is plenty of snow and frequent blizzards that you have to live and work with. Most of the time, things are pretty dry and that can affect what plant or animal life might mess with any allergies you have or it might affect the healthiness of your skin. A lot of different parts of Idaho are at higher elevations than you might be used to, and that will change how much air you get or how fast water boils (longer cooking times). Different parts of the world come with different quirks, and Idaho is no exception. One thing about Idaho you might not have considered is how you are going to get around. Idaho is not that populous of a place as compared to cities and states on the coasts and in the older parts of the country where civilization got an earlier start, and that means the infrastructure for transportation may be very different from what you might be used to. If you have lived with one way of getting around for long enough, you might find that that way no longer works.
There are two major parts to Idaho. There is the Treasure Valley, which holds some of the biggest cities in the state and stretches for a great width of the dense metropolitan area, and then there is everywhere else. Some other few parts of Idaho are pretty packed together like Coeur d’Alene, but most of the state is pretty wide open with a lot of distance between any given point you might want to get to and from. For some people, this may mean that owning a car is an absolute prerequisite for living in Idaho. Buses and trains that might take you to a more sparsely populated part of the state either do not exist or are rare enough that you may not really rely on having as many options or the ideal option you're searching for.
Where other parts of the country might have frequent taxis and ride-sharing services that you can always use to get from one place to another, Idaho can be pretty bereft of those things, and the only way to get where you need to go when you need to go there is to have a car or have a friend who is willing to share their car in some way, which can be fairly rare considering how essential cars are and how valuable they are. If you need to get from Boise to Coeur d’Alene, there is not much in-between that warrants a bus route. There are a few tourist destinations, but those are not always worth of public transportation and most of the people going to them are the kind of people that have and always use a car.
But, not everyone can afford to own, maintain and fuel a car. The auto industry can do quite a lot of fluctuating, but if you are in hard times, it does not matter what state the auto industry is in, a car is still a car and it is still expensive to have one. If you live in the Treasure Valley, your options for avoiding the need of a car are pretty extensive. There is a bus service around Boise and the surrounding area known as the ValleyRide, and it can get you from place to place with relative ease and in a comfortable time frame. If you are used to traveling by bus or similar, if you are used to traveling by some sort of tram, ValleyRide probably is not going to look all that different to you. Just pay for a ticket or pass, hop on the boss at your nearest stop, and then ride it to where you need to go, or at least to the general area. If the bus does not have the perfect schedule or stop rotation for where you need to go, it might be prudent to bring some sort of cheap personal transportation to get you that extra mile or two such as a bicycle or maybe even a scooter or skateboard if you are skilled enough to use one. It will get you some exercise and augment how quickly and easily you can get to some places.
Of course, while ValleyRide has quite a lot of similarities with the different bus and subway systems of other, larger cities and metropolitan areas, it is not as utilized as a bus system that you might find in New York or Los Angeles, and therefore in many respects, it is not as good. If you are used to one of those bus or subway systems, you might find ValleyRide severely lacking. Like any other city, there are still taxi services, but those can get expensive. If you do not need to go out frequently for work or other activities, you might be able to make a taxi work, but you also might still be better off using one of the different apps that bring rides directly to you. This can be more expensive than a bus ride, but it can get you places a bus might not go or might not go when you need it to. Unfortunately, a train is also not really an option. There are plenty of novelty trains in the area that might take you on a tour of some part of Idaho, but your options for getting place to place with a train are limited.
It may be ideal when you live in Idaho to have a car. Traffic is rarely a big issue and you will need it to get long distances when there is a need to. Other options are available and they can help for a time, with a limited amount of things.
